Application led September 21, 1915. Serial No. 51,807.

To all whom t may concern:

Be it known that I, HERBERT B. MANNING, a citizen of the United States, residing at Fall River Mills, in the county of Shasta, State of California, have invented certain new and useful Improvements in Demountable Rims; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention., such as will enable others skilled in the art to which it appertains to make and use the same.

.This invention relates to a demountable rim.

An object of theinvention resides in the provision of a rim which may be tightened upon the wheel and which will be securely held in position.

A 4furthe1 object of the invention resides in so constructing the rim that the parts thereof may be easily and quickly applied.

With these an'd other objects in view'such as will appear as my description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.

In the drawing:

Figure 1 is an elevational view -of a wheel showing the rim constructed in accordance with my invention, mounted thereon;

Fig. 2 is an enlarged sectional view on line 2-2 of Fig. 1;

Fig. 3 is an4 enlarged detail showing the manner of securing the ends of the movable ring together and showing also the stop upon the felly band;

Fig. 4 is a fragmental View of the means for securing the ends of the rim together;

Fig. 5 is a section on line 5--5 of Fig. 4;

Fig. 6 is a section on line 6-6 of Fig. 4;

Fig. 7 is a sectional view showing the wedge blocks upon the rim, and

Fig. 8 is a detail showing the manner of securing the felly band to the felly.

Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views:

In the embodiment of the invention shown in the drawing, I have illustrated a Wheel which includes a hub 1, a plurality' of s okes 2 and a folly 3. Mounted on the fell 3 is a felly band 4. A movable ring 5 having a channel therein for-thereception of the folly band 4 is mounted upon the said felly band.

The ends of this ring are secured together by means of bolts 6 which pass through ears, 7, the said bolts passing through one. of the ears of each pair freely and in threaded engagement with the other. A rubber packing 8 is interposed between the'ends of the ring 5 und the cars 7 to allow the said ring to be tightened. This ring 5 is provided with an elongated slot 9 through which a lug 10 which is formed uren the felly band 4 extends, which lug prevents the movement of the ring after it has been secured in position. Formed 'upon the ring 5 at a plurality of points, which points are'in alinement with the ends of the spokes 2 are wedge blocks 11A Mounted upon the ring 5 is a rim 12 which is provided with a plurality of wedge blocks 13, which blocks are adapted to coperate with the wedge blocks 11 on the ring to maintain the rim in place.

In order that the rim may be readily placed within a tire, 1 have formed the same in two sections and have secured one of the wedge blocks 13 to one end of the rim by rivets 14' so that the said block bridges the joint between the ends of the rim as illustrated in Fig. 4 of the drawing. The face of this block 13 which is adjacent the rim is provided with anintegral block 15 which seats in a corresponding depression in the rim 12. Pivotally mounted, at 16, on the end of the rim opposite to that to which the aforementioned block 13 is secured is a lever 17 which is provided with a cam head 18. This head is arranged to seat in a correspondingly shaped pocket in the block 13 s0 that it will maintain the ends of the rim in their locked positions as will be readily understood. The ring 5 is provided with an elongated slot 19 through which the valve stem 20 extends.

Formed on the inner face of the felly band 4 is a bur 21 with which a thumb screw 22 is engaged, which thumb screw extends through the felly and maintains the ring in position upon the same.

In applying the device to a wheel the ring is lirst secured upon the telly band with the lug 10 extending upwardly through the slot 9 in the band and with the adjacent wedge block 11 in slight spaced relation thereto. The rim is inserted in a tire shoe and the ends locked together. It is then placed upon Hw wheel. This rim is placed so that the large end of the wedge block 13 abuts against the lug 10. The cars Y are then tapped with a hummm' or other suitable ini- ]ilenient so that the wenigehloiflo; l1V will, liu forced beneath the wedge hlmzlcr#a l am! Milf thus maintain the i'ini in tight relation to the felly hand. This movement of the ring` ie: pern'iitteol because of the fac-t that the` iup; 10 extends through the :lot E) and the val'. i stem JU through the slot 1t). i

From the foregggoingjr (lefmription it uili la seen that 1 have provided a ilei'i'iouutahh rim which may he readil)` secured on :1 wheel and which will he prevented from accidental displacement.

vWhile l have illusti'ulml and described a particular einhoiliuwul o' my invention, ii has merely heen for the alie oi convenience und I do not u ish to lm' limited to that 51:11'- tcular einhoi'liuient as; it is olu'iou` that nu morons changea may la niaile in the ilveah 0f construction without departing; from liu Spirit of the invention oi' exieellingf iheww if of the :.ippeluieii claim.

What l claim is:-
